PRUNING IMPLEMENT.

in operation and avoid the use of a cord in connection therewith, which cord is liable to break.

I will describe my invention with reference to the accompanying drawings.

Figure 1 is a side elevation, partly in section, of the shears complete. Fig. 2 is a side view, partly sectional, of the shears drawn to a larger scale.

The fixed member 0 of the shears O has its lower end terminating in a ferrule g, by means of which the shears O are secured to the upper end 19' of a tubular rod P. This tubular rod P may, however, consist of a single length or preferably of several lengths, (in the drawings two such lengths p 9 are shown) united by the threaded ferrules a a or by bayonetjoints or other convenient methods. Consequently the tool can be divided into several pieces, each of relativelysmall size and conveniently portable.

The movable member 0 of the shears C has its lower end bent to engage in a link 5. The link .9 is connected at d to a rod 15, the upper end of which is encircled by a spring m and its lower end connected to a second length of rod 25 The spring m is of shape and strength suitable to the size of the apparatus and is coiled around the upper part of the rod 25 and prolonged above the head of the tubular rod'p and retained between the enlarged connection d and a collar 0, which rests upon the end of the tubular rod p and is held there by the spring m,the hole in the collar 0 being just sufficiently large to allow of the free movement of the rod 6. The said spring is formed, preferably, of a steel band coiled spirally. This band may be single or preferably, when the apparatus is large, it may be formed double of a coiled plate of V shape.

This latter construction of the spring is that shown in the drawings. The spring instead of being placed outside, as shown, may equally well be concealed in the tubular rod but I prefer an outside spring for convenience of manipulation and repair.

Each length of the tubular rod has a corresponding length of internal rod, t 15 &c., and the connectionof each piece of the rods 25 and t with the following piece may be effected by means of hooks at their ends. The spring 111, being slightly compressed, prevents these hooks from becoming uncoupled.

The lower end of the tubular rod 19 is provided with a ferrule g in one piece with the fixed member 1) of the operating-handle B. The movable member 5 possesses a guard b and a stop-screw '0, which when the handle is operated abuts against the fixed member b. In order to retain the handle Bclosed, I provide a small flexible ring 6, made, for instance, of a piece of leather secured by a screw to the movable part b of the handle B. The lower length of the rod t is prolonged alittle beyond the end of the tubular rod p and passes through a ring which moves hands applied to the handle will sufiice to uphold it. When the movable member 6 of the handle is pressed toward the fixed member b, the forked end f depresses the nuts 01 and draws down the rods 25 t and link 8. By this means the movable member 0 of the shears is also drawn down, causing the blades to meet. When the operating-handle B is opened, the spring m returns the movable parts to their original position and the shears What I claim ismy invention I have signed my name, in pres- In a pruning apparatus the combination of once of two witnesses, this 31st day of May, the screw-coupled tubular rods 19, 19 the linked rods 15, t the handle B, the spring m,

5 the shears C and the connecting-link 5, substantially as described.

In testimony that I claim the foregoing as DON SERAFINO DONZELLA. Witnesses:
